Improved washing-machine

Lette/rs .Patent No. 90,309, dated May 18, 1869.

A IMPROVED WASHING-MACHINB dore- The Schedule referred to in these Letters Patent and making part of the same.

To alliwhoml 'it may concern:

Be it known that I, J Aeon S. Ross, of Bloomingfton, in the county ol` McLean, and State of Illinois,

have. invented a new and useful improved Washing- Machine; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, which form part of this specification. y

My improved machine consists ofa revolving cylinder, of novel construction, mounted in a suitable tub, preferably constituting a boiler, so as to perform the operation of boiling and washing at the same time, and adapted to receive the clothes within it, and sub- I ject them to the combined action ofthe hot suds and steam, to cleanse them, they being agitated, meanwhile, te expose their different surfaces. -My improvements consist in the peculiar construction of washing-cylinder, whereby the above-named result-s are laccomplished, and the combination of such cylinder as constructed with a boiler, or a tub adapted to be placed over the lire, so as to perform the operations of boiling and washing at the same time.

To enable those skilled in the art to make and use my invent-ion, I will proceed to describe it more particularly, with reference to the drawings, in which- Figure l is a perspective view of a machine embodying my improvements, portions of the tub and cylinder being broken away to expose more fully their construction, and the lid of tbe former removed, and that of the latter opened, as in introducing the water or suds and clothes.

Figure 2 is a transverse vertical section of the machine, with the cylinder and tub closed, as during the operation of washing.

vlhe tub A, as constituting also a boiler, `is constructed of metal, as represented, of any suitable form, and provided with a removable or hinged lid or' cover, A', tig. 2,

Its ends are provided internally Vand at suitable points with suitable bearings a, iig. l, for lthe reception of the trunnious or pivots b. of the cylinder B, one of said ends being fmther perforated, as represented at a', iig. 1, for the reception of the crank O, by which the cylinder is rotated.

The crank C engages with a suitable angular socket in one ofthe trunnions of the cylinder, as represented, or'in other suitable manner,.and is preferably adapted to be withdrawn, to allow ofthe removal of the cylinder'wheu desired, the. bearings in which said cylinder is mounted being further made open for that pur pose.

'The cylinder B Amay be made of suitable sheetrnetal, and is provided with a door, B', hinged at one side and provided with a suitable catch at the other,l

to retain it in its closed position, as shown, through which door the clothes to be washed are introduced. Its ends are perforated with a suiicient number of holes b', preferably of large area, as shown, to allow the water and steam from the tub to fill it.

Itis further provided with an inner perforated shell, B", extending entirely around it, including the door, and forming an annular space, B', which is divided at suitable intervals, by longitudinal partitions 11', into a number of compartments or cells, each of which communicates with the interior of 'the cylinder by means of one or more rows of the pelfoiations b of the inner shell B". v

`Attached to said inner shell, as represented in iig. 2,or formed thereby, are inwardly-projecting ribs or projections 13", preferably similarly peribrated, as represented at 11", to afford communication between the annular space of the cylinder and its interior, and so arranged, when attached to the inner shell B", as to enclose one or more rowsA of its perforations, as shown, for that purpose.

In operation, the tub A, being supplied with a suitable quantity of water or suds, and the clothes to be washed introduced into the cylinder, which is also supplied with the water in the tub through the perforations b', the'tub isthen, or previously, placed over the tire or on the stove,'where it is allowed to stand until the water has 'begun to boil. p

The steam arisinnr from the water passes through the perforations b b' in the inner shell B 13" into the compartments of the annular' space B" above the surface of the water, and fills them, being retained in them by the imperforate outer shell of the cylinder and the partitions b'.

Motion then being imparted to the cylinder by means of the crank C, or other suitable means, the compartments ot' the annular space containing steam are brought below the surface ofthe water, when the water, flowing into them, forces the steam out, thus causing it to rise through the clothes. v Y

This operation is continually repeated during the rotation of the cylinder, andthe clothes are turned and' agitated by meansof the ribs B", thus constantly o bringing new surfaces to its action.

By this means I am enabled to secure the use of the boiling suds, and also to subject the clothes to the superior cleansing-action of steam, by a simple and convenient apparatus. All rubbing and straining of 1. 1 claim the revolving cylinder B, constructed To the above specification of my improved washingwith the inner perforated shell B", partitioned annular machine, I have signed my hand, this 30th day of v spaceB, and ribs 'or projeeiionszm, adapted to op- Maxeh, 1869.
